BOTTLE -CLOSUBE Specification of Letters Patent.

Patented Sept. 17. 1907.

Application filed May 3,1907- SBIiBJI To all whom it may concern:

Be it known that I, THOMAS L. CoNNoRs, a citizen of the United States of America, residing at Hudson, in the county of Columbia and State of New York, have invented new and useful Improvements in Bottle- Glosures, of which the following is a specification.

This invention relates to bottle closures, particularly of that type comprising a cap associated with an inner sealing disk and means embodying a bail and a cam lever for clamping the cap in closing position.

The object of the present invention is to provide a cap and seal especially designed for use in connection with milk bottles, by which the necessity of employing the ordinary disk fitting within a groove in the bottle neck is avoided, as well as liability of breakage of the rim edge of the neck which occurs in the use of such disk seals, rendering it necessary for large dairy concerns to replace a large proportion of the bottles in use at considerable expense, such breaking or chipping oi the rim edge being common as a result of the fragile character of the same on account of the formation of the disk-receiving groove or recess therein.

In the accompanying drawing illustrating the invention,-Figure 1 is a side elevation of a neck of a bottle closed by the improved stopper. Fig. 2 is a vertical cross section thereof. Fig. 3 is a top plan view. Fig, 4 is a sectional plan view on line 44 of Fig. 1

Referring to the drawing, 1 designates the neck of a milk bottle of ordinary construction, provided with an enlarged rim portion 2 having a basal shoulder 3, and 4, 5 and 6, respectively, designate the bail, tie-wire and lever of the ordinary bail-tie bottle stopper, which are mounted upon the bottle neck in the usual manner.

The cap 7 is provided with an eye 8 by which it is pivotally mounted on the bail, and is of concavo-convex shape and formed of sheet metal. The edge of the cap terminates in a downturned flange 9 adapted to project downwardly outside of and surround the upper portion of the thickened bead or. rim 2 of the bottle neck. Within the cap is placed a correspondingly shaped sealing disk 10, composed of waxed paper or some other suitable material, which lines the whole of the interior of the cap and has a downturned portion or flange 11 arranged between the flange 9 and rim 2 to effect a tight sealing connection.

in practice, the cap is struck up from sheet metal having sufficient resiliency to insure a firm clamping action of the flange 9 on the flange 11. of the sealing disk,

by which any possibility of access of air to the interior of the bottle when closed by the cap will be effectually prevented. To increase this spring binding action of,

the cap flange upon the seal the said cap flange is formed with an inwardly and upwardly bent rim portion 12 bearing directly against the flange 11 and designed to hold the lower edge thereof securely against outward movement. This rim portion not only strengthens and reinforces the edge of the cap flange, but by increasing the relative thickness thereof at the bearing point promotes to a material extent the springclamping action of the said flange on the flange of the disk.

By the construction described, the sealing disk will be rigidly secured ti) hermetically seal the bottle, and after being once used may be discarded and a new disk substituted therefor to reseal the bottle when it is again filled. The necessity of providing the bottle neck with the usual disk-receiving recess is also avoided, thus leaving the thickness and strength of the bead or rim 2 unimpaired, so that it is not liable to become chipped or broken.

Having thus described the invention, what is claimed as new, is:

A bottle closure comprising a sheet metal cap provided with a depending flange to inclose the rim of the bottle neck, a sealing disk having a flange adapted to be clamped against the bottle neck by the flange of the cap, the said flange of the cap being formed with an inturned rim hearing directly against the disk, and means for securing the cap in applied position.

In testimony whereof, I arhx my signature in presence of two witnesses.
